Do you know what the composition of a calculator is? Wholesale solar scientific calculator products Xiaobian will take you to a brief understanding.
Calculators are generally composed of calculators, controllers, memory, keyboards, monitors, power supplies, and some optional peripherals and electronic accessories, through manual or machine equipment. The arithmetic unit and controller of the low-end calculator are implemented by digital logic circuits for simple serial operations, and its random access memory has only one or two units for accumulative storage. High-end calculators are implemented by microprocessors and read-only memory to realize various complex operation programs, and have more random storage units to store input programs and data. The keyboard is the input part of the calculator, and generally adopts the touch or sensor type. To reduce the size of the calculator, one key often has multiple functions. The display is the output component of the calculator, such as a light-emitting diode display or a liquid crystal display. The integrated circuit is equipped with an automatic power-off circuit that does not operate at regular intervals. The optional peripheral devices of the calculator include micro-printers, cassette tape drives and magnetic card machines.
The above is the editor of Wholesale solar scientific calculator products: a brief introduction to the knowledge of the composition and structure of the calculator.
